RUDOLF BRETTNER, OF NEW YORK, N. Y.

JEWELRY.

To all whom it may concern Be it known that I, RUooLr BRETTNER, a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented a new and useful Improvement in Jewelry, of which the following is a specification.

This invention relates to improvements in jewelry, and the object is to provide a bracelet, necklace, or other article of jewelry, composed of units forming a base to which the ornamentation is attached, the units being so constructed that they may be connected without the use of solder and without the use of tools, and when assembled will form an article of jewelry which is elastic, each unit having a spring-connection with the adjacent unit.

With the above object in view, the invention consists in the novel features of construction hereinafter fully described, particularly set forth in the claims, and clearly illustrated by the accompanying drawings, in which Figure 1, is a plan view of two of the units showing one form of the invention; Fig. 2, a central longitudinalsectional view of the same; Fig. 3, an enlarged transverse sectional view on line 33 of Fig. 1; Fig. 4:, a transverse sectional view on line 4-4 of the same figure; Fig. 5, a longitudinal sectional view on the line 5-5 of Fig. 1; Fig. 6, a plan view of two of the units showing another form of the invention;

Fig. 7, a central longitudinal sectional view of the same; Fig. 8, a transverse sectional view on the line 8 -8 of Fig. 6, and Fig. 9, a longitudinal sectional view on line 9-9 of Fig. 6.

Referring to Figs. 1, 2, 3, 4, and 5, the numeral 1, designates the units, here shown as rectangular in contour. Each unit has eX- tending from one side to its opposite side, a pin or bar 2 on which there is a coiled spring 3, and on opposite sides of its center a slot 4: having portions disposed on each side of the end of the pin and a curved portion disposed about said pin. Sliding through one of these slots and projecting from the unit is a connecting-member 5 of the same contour as the slot, this member being prevented from becoming disengaged from its unit by a head 6 which lies between the wall of the unit and one end of the coiled spring. This member is formed at its opposite end, on each side of its central curved portion,

with a slot 7. Positioned within each unit and free to move on the pin 2, is a lockingmember 8, of the same contour as the slot 4:. The end-wall of this member lies between the end of the coiled spring and the head 6 of the connecting-member .5, and its movement on the pin is against the tension of said spring. This locking-member has on each side of its central curved portion, a projection 9, which projections are adapted to engage in the slots 7- of the connecting-member 5. To connecttwo units, the projecting portion of the connectingmember 5 of one is inserted through the slot 4 of the other unit and pushed toward the locking-member 8. The latter will tilt slightly until the projections 9 thereof drop into the slots 7 of the connecting-member. The two units are then yieldingly held together. The two units may be disconnected by pressing the same slightly as if to break them apart, when the projections 9 of the locking-member will disengage the slots 7 of the connecting-member.

Referring now to Figs. 6, 7, 8 and 9, the numeral 10 designates the units, each of which carries a pin 11, as in the first struc ture described, on which there is a coiled spring 12. Each unit also has formed in its opposite sides at the respective ends of the pins, curved slots 13 having side-slots connected therewith. Arranged in each unit and slidable on the pin 11, is a connect;- ing-men1ber 14:, the end of which projects from the unit and is formed with slots 15 on each side of its central curved portion. Each member 14 has formed thereon, cars 16 which act as stops to limit the sliding movement of said member. On each pin at the rear of the connecting member, is a locking-member comprising a plate 17 having projections 18 adapted to engage in the slots 15 of the connecting member of the adjacent unit. To connect the units, the projecting end of the connecting-member of one unit is inserted in the slot 13 of the other unit, and the two units pressed together until the projections 18 of the locking-plate engage in the slots 15 of the inserted end of the connecting-member.

From the above description, it will be seen that I have provided units, any nu1nber of which may be connected to form the desired article of jewelry, without the use of tools, each unit of which is yielding, so as to form an elastic article. It will be un- 'derstood that the units may be manufactured of any kind of metal and may be ornamented with any kind of ornamentation and precious stones.

' Having thus fully described my invention,

' What. I claim as new and desire to secure by Letters .Patent of the United States, is p 1. An article of jewelry composed of units, each having slots formed in opposite Walls, a coiled spring arranged in each unit,

a connecting-member slidably arranged in each and having an end projecting from one of the slots and formed in said projectingend with slots, and a locking-member arranged in each unit and slidable therein against the tension of said spring, said locking-member formed with projections to engage the'slots in the connecting-member of the adjacent unit.

2 An article of jewelry composed of units,'each having slots inits opposite Walls,

a connecting-member slidably arranged in each unit and having an end projecting therefrom andformed in saidp'rojecting -end with slots, a locking-member slidable in each unit, havlng projections to engage the slots of the connecting-member of the adjacent unit, and'a coiled spring for each unit against the tension of which the units move relatively to each other.

3. An article, of jewelry composed of units, a connecting-member carried by each unit andprojecting'th erefrom, and means carriedby each unit forengagement with the projecting member of an adjacent unit after said member has been inserted therein,

cop ies ot thls patent may be obtained for whereby to automatically detachably lock said units together.

4. An article of 'eWelry composed of units, a connecting-member carried by each unit and projecting therefrom, the projecting portions of the members having openings therein, and a locking member arranged in each unit, the locking members having projections to detachably engage the openings in the connecting members of adjacent units.

5. An article of jewelry composed of units, a connecting-member carried by each unit, means for automatically connecting said units when the connecting-member of one is inserted in the adjacent unit, and a coiled spring for each unit against the tension of which the units move relatively to each other.

6. An article of jewelry composed of units, each having slots in its opposite walls,

a connecting-member slidably arranged in each unit, a coiled spring in each unit against the tension of which said member is movable, said connecting-member having one end projecting through the slot of the unit and formed With openings, and a lockingqnember carried by each unit having projections adapted to engage the openings in the connecting-member of the adjacent unit. In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
